I am seeing really strange log file entries - today, on one of my client's sites, Googlebot attempted to visit hundreds of non-existent pages with really odd file names that have nothing to do with his business or website. For example: /ohio/wrongful_death/city_list_g.php /maine/landlord_and_tenant/l/lincolnville_landlord_and_tenant_lawyers.php /north_carolina/dog_bites/city_list_j.php and other strange url's that do not exist, and never have. There are literally hundreds of these 404 entries in today's log file. For Google to be looking for them, they must be referred from somewhere. My concern is that someone has posted all these non-existent links to my client's site - but for what reason? Does a high number of 404's affect rankings? Has anyone else noticed anything like this? I know there are bots that will look up random url's but I've never seen Google do that. Thanks for your thoughts.
